Trane RLY3697 SPST Start Relay 35 A

The Trane RLY3697 SPST Start Relay is an electrical component found in HVAC systems such as compressors and contactor controls. It is a single-pole single-throw (SPST) relay, which means that a single on/off movement is all that is needed to regulate one circuit. The relay turns on when a low voltage signal is delivered to its coil, enabling a strong current—up to 35 amps—to pass through the attached device. To put it another way, it functions as an electrically activated switch. This relay satisfies Trane systems' requirements for dependable performance because it was created especially for them.
